Torque Due to Weight

Multiple Choice

Multiple ChoiceTwo kids play on a seesaw that has mass 20 kg, length 3 m, and its fulcrum at its mid-point. The seesaw is originally horizontal, when the kids sit at the edge of opposite ends (m,_{LEFT} = 25 kg, m,_{RIGHT} = 30 kg). Calculate the Net Torque from the 3 weights acting on the seesaw, immediately after the kids sit (simultaneously) on their respective places.

B

75 N•m counterclockwise

C

150 N•m clockwise

D
